Hi,
In my opinion closing nuclear in Germany was bad from a CO2 perspective, but sort of necessary politically. Public trust in the operators was low, and they messed up so bad that the whole spectrum of political parties dropped them.
Had they been safe I am sure that Allianz or Munich Re or similar would have privately piped up and said they’ll insure them for a competitive rate. Alas here we are. Even if we had a hefty CO2 tax - I don’t think that would have saved them economically (esp. vs wind).
I believe additional nails in the coffin were:
- blunders and uncertainties around decommissioning and storage
- Simulations of the economic knock on effects of a serious incident (+ the very high plausibility of one when looking at Japan’s capabilities, committment, and track record). In effect such an event would end a good chunk of the agri industry’s competitiveness, and had a chance to make a serious dent in other industries.
- The direct cost in human lives would have been negligible (if you permit a bit of cynicism)
- The long term costs to society were not modeled afaik
Should Germany get back INTO fission when it becomes significantly safer? Maybe. Note that many of the power stations were already in extended lifetime. Would that incurr extra “restart costs”. Maybe some, but afaik Grmany was already behind a good bit in tech, so we would’ve likely switched to French, Chinese, or did something German-Russian.
But at that time people will be paying (likely significantly more than) the 90 bn projected for decommissioning. So I am skeptical a realistic case can be made, even when numbers would be for it.
Fission aside, is there anything that can “save us”?
Fusion? In my opinion less chance to make a dent in the next 50-100 years than wind alone. I like fusion, I’m friends with some people working in the research, I live in a place that profits from ITER funding, I admire the ingenuity, etc.
But even if ITER’s granddaughter turns out to be perfect it will not deliver a constant source of power, but it will be pulsing. We’re currently at 70s pulses, ITER MIGHT do 400s to 600s. Yes, that is planned so you can design demand around it - but so is wind, solar, and tide / water to a DEGREE and this is where come closer to the crucial point in my opinion:
Of course you’ll need to adapt economic activity to seasons and similar. This has been true for millions of years in every place in most critical activities, and was only not true in some places, at the height of the fossil fuel glut.
Seaonality and internittency is the absolute norm. Always on at max is not how we’ll be learning to live responsibly I’m afraid.
Some points we can do with regard to climate (German example):
- Switch from coal to gas capacity immediately (IMO keep coal as fallback, be transparent, diplomatic (Russia’s neighbors) and EU-clever with the Russian suppliers) - DUH!
- Fund some nuke r&d (decommissioning, have foot in door & help with promising concepts)
- Make tgeoretical and legal framework for a supply side driven economy, incentives to manage (economic) activity with less constant power, ICT to the rescue!
- very quietly start funding a diverse range of “thought leaders” to inform decision makers of plausible scenarios of what might happen if we start dumping sulphuric acid into the high atmosphere in an uncoordinated fashion (the most likely geo-engineering trick that people are going to pull out of the hat)
- Review technical / building / transport standards with and eye towards CO2 optimization potential. Example: if you could use more wood for housing construction, growing a lot of forests would start making sense as a carbon sink. But the risk of fire is why we simply forbid a lot of it in building codes. We could step up efforts to research tech that makes such fires less common and less catastrophic. For example: a decent (usb-)cable tester, and a practice of having non-flammable material under or near shitty electronics, or old lithium batteries.
- Research and scale potential large carbon sinks such as “seaweed landfills” that are likely to outperform trees with factor of more than 20.
- Consider legal action on behalf of future generations vs decision makers who essentially halted buildout of wind power in Germany on essentially spurious grounds (What is going to happen if you quit nukes, then drop solar (you’re welcome China!), then drop wind as well, and shield automotive? Nothing good.)
